Kappler ChemTape Chemical Resistant Tape - 60yd Length x 2" Width

Will ChemTape provide a liquid-tight seal?

ChemTape is ideal for situations where the user might be exposed to chemical splashes. ChemTape should NOT be fully immersed. ChemTape uses a pressure-sensitive adhesive, so applying a high degree of pressure is crucial for application. Do not wrinkle or fold the tape when applying.

Will using ChemTape make suits gas-tight?

No. If conditions exist that require gas-tight protection, use the appropriate protective garment.

 How should ChemTape be properly applied? In which areas should it be used?

ChemTape was designed to effectively seal the interfaces and closures of protective garments (boots, suits, gloves, etc.) for added liquid resistance and protection from chemical threats. ChemTape should be applied by hand with a high degree of pressure to the interfaces between glove and sleeve, boot and boot flap, zipper, storm flap, and around respirator masks. ChemTape should be unrolled to the desired length without wrinkling or folding, then cut with a knife or scissors. ChemTape can also be torn by hand, by pulling with considerable force rapidly at a right angle. A single continuous strip of ChemTape should be used if possible. Several wraps may be required to provide the desired coverage and performance for your specific scenario.

Is it possible to reuse ChemTape?

No. ChemTape is designed to be disposed of after a single-use.   

Does removing ChemTape affect the chemical resistance of the suit material?

ChemTape uses an especially strong adhesive to maximize the bond to the fabric. ChemTape may damage fabrics when removed, although this is generally limited to lightweight fabrics. Various factors including temperature, exposure, fabric type, and length of adherence will affect the characteristics of ChemTape removal. Users must carefully inspect their garments for signs of degradation, tearing, or damage if the suit is intended for reuse.

Will chemicals affect or attack the adhesive on ChemTape?

ChemTape’s polyisoprene-based adhesive can be affected by a number of chemicals. Proper application is crucial to ensure that only a minimal flat edge of the adhesive is exposed to any contaminants.

 What’s the difference between ChemTape and standard duct tape?

Duct tape is designed to minimize the gross leakage of air from heating, ventilation, and air-conditioning equipment (HVAC). In contrast, ChemTape is designed to minimize the influx of hazardous particles and liquids through the interfaces of protective garments. These two items have radically different intended purposes, construction, and performance.

Will ChemTape removal affect the chemical resistance of gloves or will the adhesive affect the resistance?

Most chemically-resistant gloves are either “cured” or “vulcanized,” which makes them largely impervious to rubber-based adhesives like the one used in ChemTape. Film-based gloves like 4H and Silvershield may be affected by the removal of ChemTape. Users should always fully inspect their gloves for signs of physical/chemical degradation and discard if found.

Is it possible to use ChemTape over serged or bound seams to enhance holdout?

Yes. ChemTape can be used to reinforce seams, closures, and other interfaces. Once again, the careful application of ChemTape dictates its performance.

What is the temperature service range of ChemTape?

We recommend a maximum storage temperature of 120ºF (49ºC). Note that high temperatures may affect performance. Storage for 1 month at a high temperature equates to about 1 year of storage in the recommended conditions of 73ºF (23ºC).
